Definitions

• the present invention relates to a method of manufacturing jelly products having fruit-like fibrous texture wherein a plurality of liquid materials are separately prepared, the resulted liquid materials are mixed at a temperature higher than the gelling temperature determined by the gelling agents used in said liquid materials, then the resulted mixture is cooled for gelling.
• jelly products are made imitate fruit-like texture without using textures originating from fruit pulps.
• One of typical methods is freezing/thawing method (cf: Japanese Unexamined Patent Application Gazette Nos.57(1982)-­189653 and 57(1982)-36950) More particularly, jelly is freezed to form ice crystals in a gel texture, and after making the ice crystals grow to a desired extent for partial destruction of the gel texture, the freezed jelly is thawed to form partially destroyed and partially undestroyed texture to thereby form fibrous texture as a whole.
• This method has such a deffects that a large scale installation for freezing and thawing is required when the method is worked out in industrial scale and that it is difficult to manufacture fibrous jelly products having uniform quality due to non-uniform growth of ice crystals caused by slight or subtle variations of freezing conditions such as temperature, speed, and time for freezing.
• fibrous texture is formed using some combination of gelling agents (cf: Japanese Unexamined Patent Application Gazette Nos. 59(1984)-1 59745 and 59(1984)-­159746) More particularly, fibrous texturte is formed by mixing a first liquid material containing gelatin and a second liquid material containing at least a gelling agent selected from the group consisting of carrageenan, furcellaran, low methoxyl pectin and agar-agar under acidic condition for reaction therebetween.
• gelling agents cf: Japanese Unexamined Patent Application Gazette Nos. 59(1984)-1 59745 and 59(1984)-­159746
• fibrous texturte is formed by mixing a first liquid material containing gelatin and a second liquid material containing at least a gelling agent selected from the group consisting of carrageenan, furcellaran, low methoxyl pectin and agar-agar under acidic condition for reaction therebetween.
• the deffects of these methods are that the formation of fibrous texture and furthermore solidification of the mixture of said first and second liquid materials cannot be assured depending upon slight or subtle variation of the reaction conditions such as temperature and agitation during the reaction process, since the optimum temperature range in which the fibrous textures are formed in the mixture of the first and second liquid materials is very close to the gelling temperature of the mixture.
• the inventors of the present invention have exerted their efforts to develop a new and simple method which 15 well suited for industrially manufacturing jelly products having fibruos texture in uniform quality, and achieved to complete the present invention.
• At least two kinds of liquid materials are separately prepared.
• a first liquid material contains at least a kind of proteinous material selected from the group consisting of those originating from eggs, milk and soya beens and adjusted to pH 4.0 or less.
• a second liquid material contains at least a kind of gum substance selected from the group consisting of xanthan gum, gum arabic and pullulane and at least a kind of gelling agent selected from agar-agar, furcellaran and carrageenan and having a pH value which may cause the pH value of the mixture of said two liquid materials to become equal to or less than 5.0.
• the first and second liquid materials are mixed to form fibrous textures.
• any other conventional ingredients for jelly products such as acids, sweeteners, other seasonings, flavours, coloring agents, small quantity of materials derived from fruit and/or vegetable, for example, juice, pulp, puree of fruit and/or vegetable and the like can be included in said first and/or second liquid materials, however, they can be added to the mixture of said first and second liquid materials in the form of an additional liquid material in which one or more of them are included.
• liquid materials at least one of which includes one or more gelling agents are made, they are mixed together at a temperature higher than the gelling temperature determined by the gelling agents used in said liquid materials. After all the liquid materials are mixed, the resultant mixture is cooled for gelling.
• One or more kinds of proteinous materials to be used in the present invention are selected from those derived from eggs, milk and soya beans.

• One or more kinds of gum substances to be used in the present invention are selected from the group consisting of xanthan gum, gum arabic and pullulane. These materials are available in the market.
• a first liquid material can be prepared by dispersing one or more kinds of the proteinous materials in water and adjusting its pH equal to or less than 4.0 by adding acid thereto.
• a quantity of the proteinous material should be included in a first liquid material to give a protein content equal to or more than 0.02 wt.% in the mixture of first and second liquid materials.
• the resultant liquid is heated to a temperature more than 65 °C for pasteurization.
• a second liquid material can be prepared by dispersing one or more kinds of the gum substances and one or more kinds of gelling agents into water.

• All the liquid materials other than the first liquid material are so adjusted as to cause the pH value of the resultant mixture of the concerned liquid materials to become equal to or less than 5.0.
• the selection of the gelling agents and the gum substanses to be used are determined taking by the mouthfeel, taste and texture of the final products into consideration.
• liquid materials at least one of which includes a gelling agent are mixed together at a temperature higher than the gelling temperature of gelling agents used in second liquid materials.
• prepared liquid materials are mixed and caused to form fibrous textures therein, then cooled to a temperature equal to or lower than 10 °C for gelling to prepare jelly products having fibrous texture.
